Here's a short load I use. Fiocchi hull cut to 2.5", FIO 616 primer, SG20L wad, 18 grains of WSF, 3/4 oz of shot, 20ga OS card, roll crimp or maybe the crimp talked about earlier ( I'm going to try it )give 1225 fps and 9900 LUP

I like like this load, I've only used it for skeet, but should be fine for small birds.
